![]() Okay...I have heard a little about it, but how does it work? I currently run a small reactor with RowaPhos but always like to explore other options. I know that with my current set up the RowaPhos traps the phosphate, eventually gets saturated and needs changing. Where does the phosphate go with PhosDown?

![]() Hi,
Thanks for your interest in Foz Down. The way I use Foz Down in my acro grow out system is to drip it into the overflow and let it settle out in the sump. What settles out is so fine that it is not visible to the human eye among other detritus etc. For stubborn algae problems it can be added directly to the tank. Now that I use Foz Down I don't need Rowaphos or GFO. :-) Cheers, Tim

![]() sorry Foz Down
![]() so Foz Down binds with the phosphate in the water and precipitates out? I assume you can then remove it via vaccum.

![]() No worries :-)
Yes, it binds with the Phosphate. You can vacuum it out or use a pump to suck it out. The particles are so fine that I don't worry about them as they are not visible.

![]() I believe Fozdown is Lanthanum chloride. You may want to do a search on Lanthanum chloride in reef tanks. There are some risks associated with the use of this chemical as the precipitate lanthanum phosphate could be toxic to some fish and corals if not managed carefully.

With the precipitation being so small, it's likely that it will be blown around in the tank instead of settling down so vacuuming is probably useless. Many people do 1. use a 5 micron filter sock to hopefully filter some of the precipitation. 2. Do a water change after a dosing because Lanthanum chloride reacts with phosphate instantly so you don't need to wait. 3. don't care and don't do anything since it's so small you can't see it anyway. If you do decide to use Lanthanum chloride, go slow. This stuff works on lowering phosphate and works quickly. Sometime too quick ![]() Last edited by George; 03-11-2016 at 06:21 AM. |

There is many different grades of the active ingredient and companies make different concentrations. I use a high grade and have the concentration that it is very unlikely to be overdosed. It is strong enough to last an average reef tank of 90 gallons, 6 months to a year depending on fish/food load. There is dosing instructions on my website at: http://www.oceanfreshaquarium.com/foz-down.html This product can remove Phosphate very quickly so you need to not overdo it and give the corals time to adapt to the lower Phosphate levels in your tank. I personally use the "don't care and don't do anything option" as I view the flocs as completely inert. I clean the detritus out and do regular water changes but that's it as far as flocs go. For those choosing to try to remove them I have 5 micron 4" filter socks available.

![]() You're right Ryan. Very bottom of Foz Down page if anyone else is blind like me LOL
To OP. I've always had high PO4 and low to zero NO3. I got a bottle and I dose 5 drops every other day directly into my tank in front of the overflow. PO4 went down slowly and just yesterday tested it on Hanna ULR and it read 0. Stuff works good.
